Once upon a time, celebrities relied on publicists to bail them out of a jam. Following a PR nightmare, they’d remain mum, sit back, and let the professionals do the talking.

But now that celebrities (along with the rest of us) have multiple social media platforms at their fingertips, they often thoughtlessly tweet without all the facts, share an ignorant comment that would be better left unsaid, or try and do their own PR cleanup... and fail miserably. Instant regret follows, then the tweet disappears minutes later. But when you have hundreds of thousands or millions of followers, obviously somebody is going to see it… and screenshot it… and share it for all the world to see.

It's hard to believe Twitter is still a baby at only seven years old today, since it has become so ingrained into our culture... particularly when it comes to our interactions with celebrities. So in honor of Twitter's 7th birthday, here are 7 deleted tweets from celebrities that should never have been tweeted in the first place!

It's been a while since Lindsay Lohan has had her headshot taken for a magazine cover, so... she'll have to settle for this.

Lindsay posed yesterday for prison mugshot No. 6 after pleading no contest yesterday to reckless driving and lying to a police officer. She was ordered to 90 days of lockdown rehab, her sixth attempt at getting sober in a facility, where sources say she will be treated for alcohol and prescription drug abuse.

Check out Lindsay's latest mugshot — and all her other ones after the jump!

She miraculously avoided jail time and is heading to lockdown rehab for the next 90 days, but her lawyer Mark Heller has been accused of witness tampering in the case. Rumors have surfaced that he allegedly tried to coerce LiLo's former assistant Gavin Doyle into lying on the stand.

Lindsay Lohan is getting locked up ― in rehab! The Liz & Dick star agreed to a plea deal today to stay in a “locked rehab facility” for 90 days, thanks to her car crash on the Pacific Coast Highway back in June.

Along with her treatment, she’ll also complete 30 days of community service and 18 months of psychotherapy. “She is to do 90 days at a locked rehab facility,” the judge explained. “She is not allowed to leave the facility at all.”

If most of us were in NYC and had a court date in LA that could determine whether or not an eight-month prison sentence would be handed down, we'd be on the first flight back west. Most of us are not LiLo, though. She was a no-show for one flight home this weekend, boarded another plane the next day, and exited moments before takeoff... scrambling for a private jet that is now late in getting her to court for a mandatory hearing.

During his Instagram rant yesterday targeted toward his negative critics, he took at jab at Lindsay regarding her tax problems — which he later deleted. Thanks to the beauty of screenshots and word of mouth, the insult got back to her and let’s just say she’s not too happy.
